No Toil Pre-Filter Dust Cover for Kawasaki Air Filters (PF140-51)

The NO TOIL PF140-51 Pre-Filter is a protective dust cover designed for use over a pre-oiled air filter in very dusty riding and operating conditions. It helps add an extra layer of filtration protection, reducing the amount of loose dirt and dust that reaches the primary air filter while supporting consistent airflow to the engine.
Built for Kawasaki air filter applications, this pre-filter dust cover is a practical choice for off-road motorcycles, powersports equipment, and other environments where airborne debris can quickly saturate a standard filter. The cover is designed to work with a pre-oiled filter, helping extend service intervals and simplify routine air filter maintenance in demanding conditions.
Installation is straightforward, making the NO TOIL PF140-51 a convenient replacement or supplemental filtration component for riders who frequently encounter dry trails, dusty tracks, or harsh operating environments. Use it as part of a regular filter maintenance program to help protect engine intake components from excessive contamination.
